听取from的所有指定事件 [英] Listening to all specified events of a from

问题描述

您好，



我正在构建一个对其有各种控件的表单，并且每个控件都有各种处理方法，例如onLoad，Click等。当某些方法被触发时，我需要编写一个日志条目，该特定控件的_something方法被触发。



但是，不是将函数调用添加到每个方法中，有没有办法创建一个能够对订阅所有相关控件和方法做出反应的监听器？



我已经读过一些关于发布者 - 订阅者的信息模型等，但它似乎更适合自定义事件。对于我的解决方案，我需要订阅内置事件，例如_Click，_Loading等。我不想在现有方法中添加额外的代码。







任何想法，这是否可能？







谢谢！

Hello,

I am building a form which has various controls on it, and each control has various methods that are handled, such as onLoad, Click etc. When certain methods are fired, I need to write a log entry that that specific control's _something method was fired.

However, instead of adding the function call into each method, is there a way of creating a listener that will be able to react to subscribe to all the relevant controls and methods?

I have read up a bit on publisher-subscriber model etc, but it seems to be more geared towards custom events. For my solution, I need to subscribe to "built-in" events, such as _Click, _Loading etc. I do not want to add additional code into the existing methods.



Any ideas, is this even possible?



Thank you!
